<p>The injection device particularly used in self-ignition engines comprises a fuel injection nozzle (10) and an incandescent body (20) provided with a channel (30) having on its inner surface a double heating layer (33) and intended to guide the fuel jet. The double heating layer (33) comprises an inner heating row (35) separated by means of an electric insulation (36) from a second heating row (37). The two stage heating of the two rows (35, 37) is possible both for the series coupling and for the parallel coupling. The inner row (35) reaches within a short time the ignition temperature, while the second row (37) measures a high energy density of the ceramic supporting mass (38). </p> |
